A problem with concrete joint sealer that delayed work on I-15 between Lehi and Point of the Mountain has been solved, and double crews are working to ensure the project is completed by Oct. 20 as scheduled.
Marv Christiansen, project engineer for the Utah Department of Transportation, said construction on the 3.2-mile stretch of road is 75 percent complete and the contractor has been able to overcome the month and a half setback caused by the faulty sealer."The contractor deserves a lot of credit because he's really had to put in a lot of extra effort," said Christiansen.
The $3.9 million project to replace road shoulders and do repair work has required lane restrictions and closure of the Alpine interchange.
Traffic has been crowded onto the new shoulders while work has proceeded on the lanes, giving I-15 motorists a preview of the effectiveness of the new "rumble strip" shoulder. The rumble strip is a corrugated surface that alerts drivers they have gone out of the main traffic lane. The surface causes a vehicle to vibrate and the tires to make loud thumping noises . . . similar to the sound of a flat or demolished tire.
"It's downright annoying, but it does work," Christiansen said.
